HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 350,337, dated October 5, 1886.

' Application filed Mart]! 15, 1886.

To aZZ whom it may concern Be it known that I, B. MEADE BAOHE, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Heating Apparatus, which improvement is fully set forth in the following specification and accompanying drawings, in which Figure-1 represents a top or plan view of heating apparatus embodying my invention. Fig. 2 represents a partial side elevation and partial vertical section thereof. Fig.'3 repin line a :0, Fig. 2.

' Similar letters of reference indicate corresponding parts in the several figures.

My invention consists of improvements in heating apparatus, whereby many advantages are obtained, as will be hereinafter fully set forth.

Ret'erring'to the drawings, A represents a furnace, which, in general, is of usual form B 0 represent outlet-pipes connected with the hot-air chamber at different heights and serving to direct the products of combustion from the furnace to the chinmey-fluc.

1) represents a radiator, which. consists of horizontal] y-arranged drums D D located one abovcthe other and formed of cast or wrought drum being connected with the outlet-pipe B, and the lower drum with the outlet-pipe C, said drums being also connected with each other by elbows D, whereby they are in communication,and may be made square or cylindrical, or both, in cross-section or other de sired form,the radiator, as will be seen, encircling the furnace at or near the upper portion thereof :and extending angularly around the same, although a circular or other form may be adopted.

The outlet-pipe B is provided with a valve or damper, E, whereby the products of combustion may be prevented from leaving the furnace through said pipe, and the radiator has a pipe, F, for discharge of the products of combustion therefrom.

The drums are substantially horizontal, either with the lower drums horizontal and Serial No.-19;' ,202. (No model.)

the upper drums inclined upwardtoward the rear, or else with both the lower and the upper drums inclined, the first toward the front, the second toward the rear.

It will be seen that when the fire is first made and the valve E is open the products of combustion enter; the pipe B and passing across the adjacent part of the drum-D reach the pipe F, and thence escape into the chimney-flue. \Vhen the fire is well made or in good condition, the valve E is closed and the products of combustion enter the pipe 0 and are thereby directed into the lower drum, D and thence through the elbows D into the upper drum, after which theyare discharged from the upper drum,by the pipe F, it being noticed that said products traverse the lower drum, starting at the place of j unction of the pipe 0 and then traverse the upper drum, D, from the Furthermore, the intersections of the'pipe B with the drum 1) and of the pipe F with the drum D being on the line of the center of the whole mass of metal of the radiator, these points will tend uniformly to be the hottest of any on the radiator, and, both for this reason and because thesepoints are at the same time respectively the vents into the chimney-flue, they will actually in practice be relatively hotter than usuah On account of these circumstances, therefore, from first to last of the firing of the furnace the draft will tend to be immediate and then will be rapid and continuous. Again, the radiator, owing to the the manner of the construction and disposi tion of the drums D D presents a larger ra; diating-surface by far than that supplied by the drums or other radiators in ordinary furnaces, and this without checking the draft by downward vertical movement of the air and without occupying space otherwise utilizable', and thereby necessitating the enlargement of the furnace as a whole. On the contrary, although its heating capacity is increased through the exposure of greater radiatingsurface than usual in the air-chamber, yet, coincident with this addition, the entire apparatus is about as compact as usual.

Connected with the elbows are pipes G of smaller diameter than the said elbows passing through the walls of the furnace and provided at the open outer ends with caps G, whereby easy access may be had to the interior thereof, and the dust which collects in the said pipes may be readily removed therefrom.

' I am aware that it is not new to construct a furnace with radiators partially encircling the same, said radiators leading to the flue; neither is itnew to supply the outlet-pipe with a valve whereby the products of combustion may be directed by a different channel to the flue, andsuch I do not claim.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A heating apparatus having two outletpipes leading therefrom, the upper one having a damper therein, two horizontal or approximately horizontal radiators located one above the other and connected at their ends by elbows, the lower outlet-pipe leading into the lower radiator and the upper outlet-pipe leading into the upper radiator, and a discharge-pipe leading from the upper radiator, all substantially as described.

2. The furnace A, having outlet-pipes B and C, the said pipe B having a damper therein, the horizontal radiators or drums D 17 ,10- cated one above the other, the drum 1) being connected with the outlet-pipe B, and the drum D with the outlet-pipe G, the elbows Dflconnecting said drums D D-,the dischargepipe F, connected to the drum D, dust-pipes- G, connected to elbows D" and having caps G" on open ends outside of the walls of the furnace, all combined and arranged substantial] y as described.
